6. What is the function of the stainless steel sleeves on the steam tube?
A: It can make the steam to form a vortex convection, which can make the milk foam become richer and finer.
7. Why there is water flowing out from the steam tube when adding water into the water tank?
A: After the amount of water exceeds the standard, the water will flow out from the steam tube.
8. Can the coffee machine be used to make milk foam immediately after making coffee? Is there anything that
the user need to pay attention to?
A: The user needs to pay attention to the following when making milk foam after making coffee by the coffee
machine: 1. If there is water remaining in the water tank, the knob can be switched directly to the steam
position to make the milk foam; 2. If there is no remaining water in the tank, switch the knob to the pressure
relief position to have steam pressure relief, and then to add appropriate amount of water again after the
pressure relief is completed.
9. Why the milk couldn’t be made into milk foam?
A: 1. Make sure that you choose the milk kept in cold storage; 2. The milk can not be made into milk foam
after its temperature rises due to the milk-foaming making process; 3. Making milk foam is a kind of skill.
Please practise more.
10. What should be done if the milk foam has relatively big bubbles?
A: You can take the latte art cup and knock it hard on the table for a few times, and hold the latte art cup by
hand and rotate it in a certain clockwise direction for several times. By doing so, you can eliminate the big
bubbles and make the organization of the milk more soft and dense, which will give a more dense taste.
11. What kind of milk is suitable for making milk foam?
A: Low-fat milk is easy to make foam, but the bubble and foam is slightly bigger and looser, and it also has
no dense taste. The whole milk is not easy to make foam, but once successful there will be a fine organization,
which can make the Espresso cuisine become thick and viscous. For domestic customers, we recommend
the whole milk of Nestle brand, then Yili brand and Mengniu brand (Deluxe milk excluded).
12. What should be done if there is no steam coming out of the steam tube?
A: Generally speaking, it is usually because cleaning hasn’t been done in time after making the milk foam and
the milk curdling blocks the steam tube. You can use tools such as a clip to clear it by putting it into the steam
tube from one end of the steam tube. If it is not blocked, please try to put 1: 1 vinegar with water into the water
tank, and then switch the knob to the steam position to soften the tube so as to clear it. If the above could not
solve the problem, please contact the after-sale service center for solutions.
Regular cleaning and maintenance
1. To ensure pure coffee taste, please conduct descaling, cleaning and maintenance for coffee machines after
using it for 2-3 months.
2. Please use the "Disincrustant for coffee machine" to conduct descaling of the coffee machine (The water
and disincrustant ratio is about 4: 1, or please refer to the operating instruction). If there is no disincrustant,
you can use the "citric acid" instead (The water and citric acid ratio is about 100: 3).
There is no need to put coffee powder when cleaning the coffee machine.
4. Please clean the water outlet and steam tube respectively according to the steps of making cappuccino.
5. Then use water to clean it for more than 3 times to make sure it is clean.
6. Please make sure that the coffee machine shall rest for more than 3 minutes every time in the repeating
cleaning process.
